PREMIER DECORATIONS ENERGY EFFICIENT LIGHTING REPLACEMENT
Like many UK businesses, Premier Decorations recognised the need to reduce their outgoings and that the cost of running their existing lighting while one of the largest overheads was also one of the easiest to rectify.
Their existing luminaires (400W Mercury Discharge High-Bay luminaires) are commonly specified for warehouse or empty space lighting where installation occurs prior to occupancy. This type of fitting is not designed for racking aisles and is therefore very inefficient when used in this context often mounted too high and poorly postioned for owner/occupier designed racking layouts.
Premier chose to upgrade their Wrexham Warehouse lighting in order to reduce their overall power consumption and reduce their CO2 emissions so after considering their options chose Luxonic Lighting with AKD being appointed the project installation.
Luxonic lighting proposed their ‘Ailselux’ louvre technology with Osram lamps and control gear because the Aislelux luminaire has a superior high efficiency louvre at over 90% efficient and the average life of the high frequency dimming control gear, when used in this fitting, is 100,000 hours thereby reducing ongoing maintenance.
The fittings installed were replaced on a one-for-one basis so the same quantity of fittings were required to produce an improved working environment with significantly reduced energy consumption.
Each fitting was equipped with presence detectors. This allows a minimum light level of 10% to be maintained in the aisles when unoccupied. When an operative enters the aisle the light fittings above where they are working go to full output. After they have vacated that space or area, the lights soon return to minimum level.
Also included in the sensor is a light level detector to prevent the lights from turning on if there is sufficient daylight.
In addition to the improvements in efficiency and cost savings, the new fittings provide an improved light colour that has enhanced the quality of the working environment from that of the previous lighting system.
